Jill Martinelli and Sabine Le Guyader started making deep impressions as teenagers, never expecting that hand-casting dental prosthetics would lead to successful careers in jewelry.

Now the Massachusetts College of Art and Design graduates behind the sought-after Lady Grey jewelry line are making another kind of impression.

Like making Beyoncé smile with their thought-provoking creations.

The pop superstar has taken a shine to several Lady Grey pieces recently, most prominently a four-finger lattice ring from their spring 2014 collection.

“She’s worn them on stage and then in real life too,” said Martinelli, still gleeful about a Beyoncé Instagram post of the singer’s ringed-hand spooning a bowl of soup. “It’s exciting to see anybody wear our pieces, but you know with Beyoncé it has to go through so many people to get to her.”
